External position displacement sensor
Versions with flameproof enclosures may not be operated with an external position
detection system.
The aforementioned measures are not adequate in some applications. For example,
continuous and strong vibrations, high or too low ambient temperatures and nuclear
radiation.
The position displacement sensor and the control unit are mounted separately for these
applications. A universal component is available for this purpose. It is suitable for part-turn
and linear actuators. You will require the following:
● An external position detection system with the order number C73451-A430-D78
● Or a contactless explosion-proof non-contacting position Sensor (e.g.6DR4004-6N).
● A positioner
● A three-pole cable to connect components.
● An EMC filter module with the order number C73451-A430–D23 is provided in a set along
The EMC filter module is always used for the control unit whenever an external position
sensor is used instead of the external position detection system. An external position sensor
is, e.g. a potentiometer with a 10 kΩ resistance or a non-contacting position sensor.
